Short read. Global warming is causeing the earth\'s inner core to also get hotter.
Quite frankly, that\'s extraordinarily ignorant.
You see, heat transfers only one way: from warm areas to cold areas. You cannot heat up something that\'s 300 degres with something that\'s 50 degrees.
Just a few dozen miles down, rock is glowing with the heat. A few more dozen miles down, and you\'re into the molten rock that makes up the mantle. Hundreds, thousands of degrees. Earth\'s heat transfer is quite steadily outwards from the core, and will be that way until the decaying radioactives driving the planet\'s heating finally run out.
The hottest sun-powered temperature ever recorded on Earth was about 121 degrees F. Lava runs upwards of 800 degrees.
Any heating done by the sun during the day is bled off during night, although atmospheric conditions will affect this. This is why deserts can be 110 degrees in the daytime, yet be freezing at night--the clear air lets heat radiate into space quite readily.
The miniscule amount of heat that the sun transfers to Earth every day is retransmitted back into space every night. The amount of heat that bleeds off the core to the planet\'s surface is likewise transmitted into space at night. The planet has long been at thermal equilibrium.
Blowing up Earth (Alderaan-style), would require sudden energy increase of 1e38 joules--about what the entire sun produces in 7 years. 23 sextillion megatons.
